Topic:Clinical Symptoms
Clinical symptoms in horses encompass a range of observable signs that may indicate underlying health issues, such as disease, injury, or physiological stress. These symptoms can vary widely depending on the condition and may include changes in behavior, appetite, respiratory patterns, or physical appearance. Common clinical symptoms in horses include lameness, colic, coughing, nasal discharge, and changes in body temperature or heart rate. Identifying and interpreting these symptoms is an essential aspect of equine veterinary practice, as they provide critical information for diagnosis and management of health conditions. This page compiles peer-reviewed research studies and scholarly articles that explore the identification, assessment, and implications of clinical symptoms in equine health management.
Diaphyseal angular deformities in three foals. Angular limb deformities in 3 foals were found to originate in the diaphyseal region of the 3rd metacarpal (2) and metatarsal (1) bones. In each case, treatment consisted of wedge ostectomy followed by compression plating. Two foals survived for useful performance; the 3rd was euthanatized because of ischemia of the operated limb. The condition appeared to resemble a similar syndrome in man involving tibial curvature.
Uroperitoneum in the foal. The case records of 22 foals with uroperitoneum were reviewed. The most common cause was a defect in the urinary bladder. A sex predilection for males was apparent. Clinical signs were tachycardia, tachypnea, and abdominal distention. The history pertaining to micturition was variable. Hyponatremia, hypochloremia, and hyperkalemia were marked. A reliable means of diagnosis was considered to be the demonstration of a wide disparity in serum and peritoneal fluid creatinine values. Surgical repair was successful in 11 of 18 cases, although surgical and anesthetic complications were common. Some o...
Pathologic changes in 3-methylindole-induced equine bronchiolitis. The pathologic features of bronchiolitis were studied in horses and ponies from 30 minutes to 27 days after an oral dose of 3-methylindole (3MI). From 30 minutes to 3 hours, lesions were limited to nonciliated bronchiolar epithelial (Clara) cells, which lost apical caps and cytoplasmic granules and had dilated smooth endoplasmic reticulum (SER). At 12 hours, necrotic Clara cells were exfoliated; degeneration and necrosis were evident, in bronchiolar ciliated cells. Rare epithelial cells with hyperplastic SER appeared on the denuded basal lamina at 24 hours. Inflammatory cells, epithelia, fibro...
[A pony with “false” colic]. Report on the case of a pony with colic submitted a to the department of internal medicine. However, the animal was found to be affected with dilatation of the oesophagus which had given rise to acute pleurisy resulting from rupture of the wall of the oesophagus. The diagnosis was established after death.
Relapsing idiopathic thrombocytopenia in a horse. TEIROMBOCYTOPENIA can be caused by failure of production or increased destruction of platelets, resulting in a bleeding diathesis, characterised by mucosal petechiac and haemorrhage into various organs. In humans, some drugs (cg, phenylbutazone and chloramphenicol) cause idiosyncratic marrow suppression and subsequent thrombocytopenia. Bone marrow suppression is also well documented in humans and small animals receiving cytotoxic drugs (Calabresi 1979; MacEwen 1980). Decreased megakaryocytic proliferation is rarely recognised in large animals. The most prevalent causes of thrombocytopenia are ...
Effects of transportation, surgery, and antibiotic therapy in ponies infected with Salmonella. Seventeen ponies were infected with Salmonella typhimurium and then 15 were variously stressed by transportation and/or surgery and 9 were given oxytetracycline. Indications of Salmonella reactivation occurred in all the stressed ponies. Diarrhea due to a reactivation of the Salmonella infection did not develop until greater than 3 days after stress, although maximal shedding of organisms occurred within 24 hours. A neutropenia generally occurred within 24 hours after stress and lasted about 5 days. A rectal temperature greater than 39 C usually did not occur. An increase in serologic titer wa...
Cutaneous onchocerciasis in the horse: five cases in southwestern british columbia. Five horses were presented because of a dermatitis of the forehead. Unlike previous reports, ventral midline dermatitis was not the major problem, and was present in only two of five cases. All five horses responded to levamisole therapy at a daily dosage of 5.5 g for one week. Owners were cautioned that repeat therapy may be necessary.
Neuroepithelial tumor of the optic nerve in a horse. A nine-year-old horse was presented with severe exophthalmos of the right eye and a large mass in the vitreal cavity. The affected globe was enucleated and two months following surgery the horse was euthanized because of spread of the tumor into the calvarium producing compression of the brain stem and neurologic signs. Examination of tumor tissue by light and electron microscopic examination showed a mixed neoplasm of primitive neuroepithelium.
Clinical aspects of lymphosarcoma in the horse: a clinical report of 16 cases. This paper describes the clinical and laboratory findings in 16 horses suffering from lymphosarcoma and the autopsy results in 13 of these cases which were examined at the Large Animal Medicine Clinic, State University of Utrecht, from 1969 to 1981. The cases were classified into four groups, designated multicentric, alimentary, thymic and cutaneous forms, according to the situation of the tumours.
Navicular disease in the horse. The subchondral bone pressure. The subchondral bone pressure in the navicular bone of horses with navicular disease is compared with corresponding pressures in normal horses. An increased intraosseous pressure and a lengthened pressure drop time was demonstrated in patients with navicular disease, which indicates the existence of a venous stasis. Compared with similar investigations in humans with arthrosis it is concluded that navicular disease is a condition resembling arthrosis. The classical clinical symptoms are explained as an expression of resting pains. Treatments are suggested which theoretically can render the pat...
[Experimental reproduction of lactic acidosis in the pony]. One pony has been subjected to the intravenous injections of L-lactic acid. Two other ponies have been trained to intracaecal administration of L-lactic acid or sucrose. The obtained results show that: Intravenous injection of lactic acid increases the concentration of histamin and lactic acid, decreases the level of magnesium and reduces the pressure of carbon dioxide in the blood (the control animals and the treated animals) without the clinical symptoms of lactic acidosis. Intracaecal administration of lactic acid induces a high liberation of histamin in the caecum (the control animals and ...
